The heating and hotwater industry has seen a number of changes since the introduction of the EU’s ErP Directive in September 2015. With the aim to reach a 20% energy use reduction target by 2020, we sat down with experts Ideal Commercial Heating and Stiebel Eltron to discuss how the changes could affect you.


Under the 2015 Directive, blown gas and pressure jet oil boiler bodies under 400kW were allowed to be sold without a burner as a replacement part in a like-for-like install, where installers could re-use the existing burner.

From January 1st 2018, manufacture of these boilers must come to an end, meaning affected ranges will only be available until stock has sold out.


The next phase of the ErP Directive focuses on NOx emissions and all boilers will need to meet strict emission limits from September 26th 2018.

Natural gas and LPG boilers will need to meet a limit of 56mg/kWh, while the requirement for oil-fired boilers is 120mg/kWh.

Local space heating

Lot 20 says all local space heaters (that means electric, gaseous and liquid fueled, and includes underfloor heating and gas fires) must comply with a minimum efficiency standard, from January 1st 2018.

The aim is to reduce the consumption and emissions from local space heaters, without increasing the cost of purchase or operation. This could mean all products have integral 24 hours/7 day timers and controls, including window detection, in future.

What does this mean for you?

You may see some minor product changes but overall, 2018’s changes don’t need much from you – just make sure you’re aware of them.
